I think it's a starting point for me to go by.  I'm an AD newbie and DNS
rookie so I don't completely understand the root and production.  I assumed
you needed one domain for internal.  My only comparison to all this is the
Novell 4.x NDS.

I'm not sure I understand your question, but here goes. Rather than running
split brained DNS (which we can easily do), one of our design criteria was
to dissociate the AD domains from the company name.

Internally we purchased a relatively generic pair of domains - matching .com
and .net domains to be precise - and use .net for the root and .com for the
production. These names have abosolutely NOTHING to do with the company
name[1]. All internal systems fall into one of those two domains.

Externally - in other words anything that is publicly exposed, is in
inovisinc.net. This includes all DNS, mail and proxy hosts, but not our web
servers (they're hosted by a third party).

Our MXs are ns1.inovisinc.net through ns4.inovisinc.net, and each of them
should at this point reverse correctly. Our internal mail relays, which are
referenced by our internal domain name, all have valid reverse DNS entries
pointing to inovisinc.net addresses.

Clear as mud?
